Low-voltage and security systems estimating services for structured cabling, pathways, data outlets, racks, cameras, access-control devices, intrusion devices, and documented system components. Takeoffs support pricing from issued plans, diagrams, schedules, and specifications without system engineering, programming, cybersecurity, or commissioning.
Tools Used in Our Estimating Workflow
- Trade Scope
Low Voltage & Security Systems Scope We Estimate
Our low-voltage and security scope follows the issued technology plans, risers, diagrams, schedules, device layouts, pathway information, specifications, and documented system boundaries.

Copper and fiber cabling, data outlets, patch panels, racks, cabinets, cable tray, conduit, supports, and documented pathway components.
-
Video Surveillance and Access Control
Cameras, mounts, head-end equipment, card readers, door contacts, request-to-exit devices, lock interfaces, and documented devices.
-
Intrusion, Intercom, and Specialty Systems
Intrusion devices, intercom stations, paging interfaces, audiovisual pathways, clocks, and other documented low-voltage systems.
-
Pricing and Bid Documentation
Device counts, cable allowances, pathway assumptions, alternates, marked plans and risers, inclusions, exclusions, and pricing support.
Low Voltage & Security Systems Estimating Considerations
- Technology plans, risers, device schedules, floor plans, door hardware, electrical pathways, details, specifications, and owner standards must be coordinated.
- Cable type and length, pathway, rack location, device mounting, head-end equipment, network topology, power requirements, and door interfaces affect quantities.
- Programming, licensing, cybersecurity, testing, commissioning, fire alarm, electrical power, door hardware, and owner-furnished equipment require clear boundaries.
- Pricing depends on system manufacturer, device model, cable type, pathway assumptions, labor rates, project location, lead times, and current vendor information.

Frequently Asked Questions
Find answers about trade scope, required documents, pricing inputs, deliverables, revisions, and what happens before estimating work begins.
What low voltage & security systems items can be included in the estimate?
Depending on the drawings and confirmed scope, the estimate may include structured cabling, fiber, data outlets, racks, cabinets, pathways, cameras, access-control devices, intrusion devices, intercoms, and documented head-end components. The quotation will identify the documents reviewed, the coverage included, and any assumptions or exclusions that apply.
What documents should I submit for a low voltage & security systems estimate?
Submit technology plans, risers, diagrams, device schedules, floor plans, door hardware information, electrical plans, specifications, addenda, and owner standards. If important information is missing or conflicts across documents, we will identify the issue before or during the estimating work.
Can material, labor, or equipment pricing be included?
Pricing support can be included when requested and supported by the available information. Relevant factors may include cable type and length, pathway, device model, rack and head-end requirements, labor rates, project location, manufacturer selection, lead times, and vendor information. Actual supplier, manufacturer, subcontractor, and purchasing quotations may differ.
Can I request only part of the low voltage & security systems scope?
Yes. The assignment can be limited to structured cabling, video surveillance, access control, intrusion, pathways, a floor or system, or another clearly defined low-voltage package. The exact limits, deliverables, and pricing basis are confirmed after the submitted documents are reviewed.
How are addenda and drawing revisions handled?
Provide revised technology plans, risers, device schedules, door interfaces, equipment selections, addenda, and a summary of changed devices or pathways. We will review the effect on completed or in-progress work and confirm any additional fee or delivery adjustment before revising the estimate.
What is not included in the low voltage & security systems estimating service?
Unless expressly included in a separate written scope, the service does not provide system engineering, network design, cybersecurity, programming, software licensing, commissioning, code certification, shop drawings, or stamped documents. Estimates support bidding, budgeting, procurement, and scope review, but they do not guarantee a contract award or final construction cost.
